Spring practice is off and running in the Big Ten, as Michigan took the field Tuesday and Northwestern followed on Wednesday. We're taking snapshots of where each team stands at each position group.

We've already discussed the quarterbacks -- and will have much more on the way -- so the series begins with the running backs.

Illinois: The Illini are in a bit better shape here than they were the past two springs, as veterans Josh Ferguson and Donovonn Young both return. Ferguson averaged 5.5 yards per carry and added 50 receptions for 535 yards as the primary playmaker for Illinois' revamped offense. Young added 376 yards on 93 carries. The Illini are looking for others behind the top two, and Dami Ayoola is back with the team after being dismissed in September for a rules violation.

Indiana: Tevin Coleman quietly put together a superb sophomore season and leads the Hoosiers' running backs in 2014. Coleman provides big-play ability after averaging 7.3 yards per carry with 12 touchdowns on only 131 attempts in 2013. Indiana loses Stephen Houston but brings back veteran D'Angelo Roberts, who will play behind Coleman. Younger players such as sophomore Laray Smith could get a look here.

Iowa: Not only did the Hawkeyes toss AIRBHG to the side and get through the season without any major injurie, but they bring back everyone for 2014. Senior Mark Weisman leads the contingent after rushing for 975 yards and eight touchdowns last fall. Jordan Canzeri came on strong late in the season and is showing no effects from his ACL tear in 2012. Veteran Damon Bullock also returns to the mix, and Iowa has talented younger backs such as LeShun Daniels Jr. at its disposal. Good situation here.

Maryland: The Terrapins wide receivers tend to get more attention, but the team also returns its top three running backs from 2013 in Brandon Ross, Albert Reid and Jacquille Veii. Maryland also regains the services of Wes Brown, who finished second on the team in rushing as a freshman in 2012 before being suspended for all of last season. Joe Riddle is back in the fold as well. The group brings different strengths, from power (Brown) to speed (Veii) to a mixture of both (Ross, Reid).

Michigan: Sophomore Derrick Green enters the spring as the frontrunner to be Michigan's lead back, although coach Brady Hoke wants to ramp up competition everywhere. The Wolverines struggled to consistently run between the tackles, but the 240-pound Green could change things. Hoke also is excited about another sophomore, De'Veon Smith. Michigan moved Ross Douglas from cornerback to running back, and Justice Hayes and Wyatt Shallman also are in the mix. "We've got more depth," Hoke said.

Michigan State: Things look much more promising than they did last spring, when the Spartans ended the session with a linebacker (Riley Bullough) as their top back. Jeremy Langford emerged as a very solid option during the season, rushing for 1,422 yards and 18 touchdowns. He's back as the clear-cut starter, and Nick Hill also returns. It will be interesting to see if Gerald Holmes makes a push, or whether Delton Williams remains on offense.

Minnesota: Here's another team that finds itself in very good shape at running back entering the spring. David Cobb leads the group after rushing for 1,202 yards and seven touchdowns as a sophomore. Veterans Donnell Kirkwood and Rodrick Williams Jr. are still around, and highly touted redshirt freshman Berkley Edwards will take the field after missing last fall because of knee and ankle injuries. Perhaps the best news will come in the summer as decorated recruit Jeff Jones arrives.

Nebraska: Notice a theme here? Nebraska is yet another Big Ten squad that can feel very good about its running backs entering the spring. Ameer Abdullah elected to bypass the NFL draft for one final season at Nebraska, where he led the Big Ten with 1,690 yards on 281 carries as a junior. Abdullah will contend for national awards in the fall. Imani Cross, who rushed for 10 touchdowns last year, is one of the nation's top backups. Terrell Newby and others add depth behind the top two.

Northwestern: Top back Venric Mark (ankle) will miss spring practice following surgery, and reserve Stephen Buckley (knee) also is rehabbing, but Northwestern has no reason to panic. Treyvon Green, who filled in well for Mark last season with 736 rushing yards, will get much of the work. Warren Long also is in the mix after appearing in seven games as a true freshman. Northwestern also loaded up at running back in recruiting to solidify the position for years to come.

Ohio State: This will be a position to watch in the spring as Ohio State must replace Carlos Hyde, who was nearly unstoppable during Big Ten play last fall. Veteran Jordan Hall also departs, and Rod Smith will be the veteran of the group despite only 83 career carries. The Buckeyes have some talented young backs, from Dontre Wilson, who saw significant playing time last fall, to Bri'onte Dunn, Ezekiel Elliott and Warren Ball. Keep an eye on Elliott, who averaged 8.7 yards per carry in limited work last season but could emerge this spring.

Penn State: If it feels like Zach Zwinak and Bill Belton have been competing for carries forever at Penn State, it's because they have. Zwinak and Belton have been part of Penn State's running back rotation for the past two seasons and enter another competition this spring with talented sophomore Akeel Lynch, who rushed for 358 yards on only 60 carries last season. It will be interesting to see how much Lynch can push Zwinak and Belton in the team's first spring under a new coaching staff. Penn State has depth issues at several positions, but running back isn't one of them.

Purdue: The Boilers finished 122nd nationally in rushing offense last season, so the fact all of their running backs return might not spark mass celebration. Senior Akeem Hunt leads the group after recording 123 of the team's 319 rushing attempts in 2013. Other veteransBrandon Cottom and Raheem Mostert also are back, along with younger ball-carries such as Dayln Dawkins and three backs -- Keyante Green, David Yancey and Keith Byars II -- who redshirted last fall and could have much bigger roles.

Rutgers: Here's yet another team that returns basically its entire stable of running backs for spring ball. Paul James is the name to watch, as he rushed for 573 yards in the first four games last season before suffering a leg injury. James' health is a concern for Rutgers, which could also turn to Justin Goodwin, who showed some flashes following James' injury. Savon Huggins, who entered last season as the starter before losing ground, is in the mix as he looks to re-establish himself on the depth chart.

Wisconsin: How many teams can lose a 1,400-yard rusher and still claim to have the best running back group in the Big Ten? James White is gone, but Wisconsin remains in very good shape in the backfield. Melvin Gordon bypassed the NFL draft for another year in Madison after rushing for 1,609 yards and 12 touchdowns on only 206 carries. Gordon should move into more of a featured role beginning this spring, although he'll be pushed by Corey Clement, who had 547 yards and seven touchdowns on only 67 carries. Jeff Lewis provides another option behind the top two.
